It's 2021. There is no reason cars should be able to speed at all if every gimmick drone from Amazon can refuse to fly into protected airspace. Half of HN is expecting that by 2025 they will sell their car and permanently ride on some Waymo taxi; are they going to reach over the separator and push down on the gas pedal, if one exists anymore? No, nobody will give a fuck that the thing is doing 20mph in a 20mph zone. We can have that today even we can't have the autonomous driving part.
